If you're working on the side, then that typically also means you're going in cheaper than a licensed contractor. Which also means you have some room to spare, money wise, that is.

If you are a licensed contractor, it might be the difference between getting that job or losing the bid.

I just call it cheap insurance. I don't want to have to go back I do some of the stuff on the side I work for a school district now and I do replacement so for some side money. I really really really don't want to have to go back for any reason!! So far as been working been nice to know that I can go with the minimum 5 ton jobs if it ever come my way they want 60 amp maxi fuse size and I can get away with a number 8 and be good

Only if there's a left Winger in there who's telling me how great Obama was. But I understand about jobs being really tight it would be tough to lose a job over a few Pennies on going from number 10 and number 8 but I've lost service contracts for a whole year over $50 even though they were very content with our service I know what you mean

Bigger wire, bigger conduit, more money for the fittings [and junction boxes], more labor, etc. It all adds up.

On a bit of a tangent, here's one for you. Years ago, we learned that we cannot compete with the pricing of an electrician. Couldn't even get close. So, when an electrician was also bidding something, we stopped trying.

What do you think the difference was?

It was the mark up on materials. The electricians were selling stuff at cost. We were marking it up. Stupid electricians were leaving so much money on the table it was ridiculous. Things may have changed, I'm doing different stuff these days.

I would be telling the contractor voiding my warranty if the electrician doesn't change the feed. I've seen too many problems. Electricians going to run things on minimum wiring minimum ampacity already know there's going to be problems cuz I've just seen it too many times. And that video was wrong he actually was putting 30.1 amps on a number 10 when it should have been Max 27 inductive loads as you know job much more amps and if I'm having an issue with my brand new equipment and electrician around the minimum I'm void my warranty then I'm not going to tell you in an apart to look for a problem that doesn't exist because electricians went cheap

And he'd look at you and laugh because you refuse to LEARN the why's and wherefore's. What you've seen are problems caused by an improper install or other issues that were never addressed properly.

Because the wiring can't really handle the lock rotor amps very well. And 30.1 is too many amps on a number 10 27 Max 80% is all you're supposed to run for continuous.

80% max is resistive loads only. NOT MOTORS in an intermittent application.

Since you guys think that the wire size only with the current once you wire your stove or your dryer to a number 12 and see what happens and put the 40 or 50 amp breaker in there in fact make it a number 14 wire

You really are of dense substance...

are we talking electric units? Because both as gas would run just fine on 12. If electric units, they are resistive and follow a different code.

What wire size would be required for a 240 single phase 1,000 amp electric heat strip?

That must be for an electric boiler read the name plate. Glad you're on the west coast you didn't have to deal with New York abortions like I have. Electrical contractors go to Home Depot these days for the electric. I bought a 500 spool number 8 wire for $150. It's just super cheap at their Home Depot. I could run most number 8 HVAC for probably under $300 for everything. That's if I feel like dealing with it. Just depends on how difficult it is sometimes I don't want to deal with it so I'll have an electrician come in and do it. And the guy use does it on the side too!!! And I think about all the low life residential pieces of s*** I've worked for in the past and I think to myself I got this money it's all mine. You lose so there's a really good revenge for me when I do it.

In in NY and these "problem jobs" as you call them pass just fine in my towns. We have some of the most particular inspectors around.

Pay attention, be humble, admit when you're wrong, and you'll go far on here and in your career.

With the right palm grease you can get it passed because I've seen it

I dont believe in that kind of work.

There's members on here that Ive worked with in the past. I saw them get failed for minutia that amounted to nothing in the scheme of things. Plus, they got cited on things that arent even their purview. I'd think that one of the largest companies in NY should be able to grease a few palms, huh? Apparently, they dont work that way either, nor should they.

The only reason for "greasing palms" is to get your substandard and crappy work passed.
